[Vol. 6 



Body elongate oblong, very fiat. Head short with five slender spines, those in 

 front nearly extending to beyond the second antennal joint, the other two diverging 

 from the base of head somewhat upwardly. Eyes rather small, globular, reddish, 

 strongly faceted. Bucute minutely reticulated, the edge hardly upturned. Sides 

 of rostral groove moderately raised; rostrum not quite reaching the metastemum. 

 Antennae long and rather thin; basal joints about as long as the apical, which is 

 fusiform; second joint very short; third, four times as long as the fourth. Pronotum 

 narrowing anteriorly, the disk hardly convex, with three linear, low carina;; inter- 

 spaces finely punctured; the triangular posterior portion of pronotum quite long, 

 pointed at apex, the surface depressed, closely reticulate; the expanded lateral 

 margins of pronotum are formed by two layers of membrane joined together on the 

 outer edge (viewed sideways) which is cut straight and rectangular anteriorly, the 

 lateral margins are somewhat opaque and have two rows of small areoles. Hood 

 short and with a sharp carina on top, projecting a little in front, but not covering 

 the head, finely reticulated. The elytra transparent, elongate-oval in shape, extend- 

 ing to far beyond the abdomen, the sides feebly rounded, narrowing slightly toward 

 the apex; discoidal area very long, reticulate, the inner nervure, bounding the area, 

 more sharply defined than the outer one, another smaller vein passes along the 

 disk nearly parallel to the inner nervures; subcostal margins narrow, biseriate, 

 costal margins a little broader than the discoidal area with irregular rows of hexan- 

 gular areoles, those nearing the apex of elytra larger; at the sides anteriorly three 

 or four transverse depressions or folds. Integument pale stramineous; pronotum 

 and abdomen ochraceous; antennae and legs yellowish-white, claws black. Length 

 3.8 mm.; width across the widest part of elytra 1.6 mm.
